Embodiment
The embodiment of magnet detection device described in the utility model is described below with reference to the accompanying drawings.Those of ordinary skill in the art can recognize, when not departing from spirit and scope of the present utility model, can revise by various different mode to described embodiment.Therefore, accompanying drawing is illustrative with being described in essence, instead of for limiting the protection domain of claim.In addition, in this manual, accompanying drawing draws not in scale, and identical Reference numeral represents identical part.
Fig. 2 is skeleton view, shows outer shape and the structure of the magnet detection device described in an embodiment of the present utility model; Fig. 3 is circuit diagram, shows the magnet detection circuit in the magnet detection device described in this embodiment.
As shown in Figures 2 and 3, the magnet detection device 100 described in an embodiment of the present utility model comprises: base 10, holding tank 20 and the magnet detection circuit 30 be arranged in base 10.
Shape and the structure of base 10 are not particularly limited, and detect portable type electronic product, handled easily person be operating as suitable to facilitate.
Holding tank 20 is formed in base 10, for holding portable type electronic product 200 to be measured, wherein, has magnet setting position 210 in this portable type electronic product 200 to be measured.Under normal circumstances, portable type electronic product 200 to be measured is provided with predetermined magnet at this magnet setting position 210 place.
Magnet detection circuit 30 is arranged in base 10, and as shown in Figure 3, magnet detection circuit 30 comprises: power supply 31, magnetic switch 32, substandard products pilot lamp 33 and certified products pilot lamp 34.
Magnetic switch 32 is a kind of conventional circuit switches controlled by field signal, and it comprises magnetic induction portion (not shown) and three terminals (i.e. common port a, normal-closed end b, Chang Kaiduan c).When the magnetic induction portion of magnetic switch 32 does not sense magnetic field, its common port a is communicated with normal-closed end b, and when the magnetic induction portion of magnetic switch 32 senses magnetic field, its common port a is communicated with normal beginning c.In the present embodiment, the magnetic induction portion of magnetic switch 32 is near holding tank 20, and as shown in Figure 3, the common port a of this magnetic switch 32 is connected with one end of power supply 31, and its normal-closed end b is connected with the other end of certified products pilot lamp 34 with power supply 31 respectively by substandard products pilot lamp 33 with normal beginning c.
When not holding portable type electronic product 200 to be measured in holding tank 20 or accommodate the portable type electronic product 200 to be measured not containing magnet, the magnetic induction portion of magnetic switch 32 can not sense magnetic field, thus, the common port a of magnetic switch 32 is communicated with normal-closed end b, thus makes substandard products pilot lamp 33 luminous.Substandard products pilot lamp 33 luminescence just shows that portable type electronic product 200 to be measured is not equipped with determined magnetic body, because of but underproof product.
When accommodating the portable type electronic product 200 to be measured containing magnet in holding tank 20, the magnetic induction portion of magnetic switch 32 will sense magnetic field, and thus, the common port a of magnetic switch 32 is communicated with Chang Kaiduan b, thus makes certified products pilot lamp 34 luminous.Certified products pilot lamp 34 luminescence just shows that portable type electronic product 200 to be measured is equipped with predetermined magnet, because of but qualified product.Substandard products pilot lamp 33 and certified products pilot lamp 34 can adopt the LED of different colours, remind operator to facilitate.
The magnetic field sensed in order to the magnetic induction portion of magnetic switch 32 when making to insert the portable type electronic product 200 to be measured containing magnet in holding tank 20 is the strongest, the shape of holding tank 20 preferably with the form fit of the portable type electronic product to be measured 200 that will hold, make portable type electronic product 200 to be measured can only insert in holding tank 20 by predetermined orientation, in addition, the setting of magnetic induction portion in base 10 of magnetic switch 32 should make, when portable type electronic product 200 to be measured inserts in holding tank 20 by described predetermined orientation, the magnet setting position 210 of magnetic induction portion in this portable type electronic product 200 to be measured of magnetic switch 32.
In order to save electric power, as shown in Figure 3, power switch 35 can be serially connected with in one end of power supply 31 or the other end.Like this, when magnet detection device 100 does not detect, turn on the power switch 35, cut off the electric power supply of magnet detection device 100.
In order to remind operator more easily, as shown in Figure 3, can also on certified products pilot lamp 34 hummer 36 in parallel.Like this, when magnet detection device 100 detects the portable type electronic product 200 that magnet is housed, while certified products pilot lamp 34 luminescence, hummer 36 sends buzzing, thus makes to prevent operator from producing erroneous judgement because of tired.
According to above description with put into practice known, when adopting magnet detection device of the present utility model to detect in portable type electronic product whether predetermined magnet has been installed, only this electronic product need be inserted on this pick-up unit in holding tank, then see it is that certified products pilot lamp is bright, or substandard products pilot lamp be bright.If certified products pilot lamp is bright, then can judge that this portable type electronic product is equipped with predetermined magnet, be certified products, if substandard products pilot lamp is bright, then can judge that this portable type electronic product is not equipped with predetermined magnet, be substandard products.Therefore, the advantage adopting magnet detection device of the present utility model detection portable type electronic product whether to install predetermined magnet is that accuracy is high, efficiency is high, labour intensity is low.
Describe in an illustrative manner according to magnet detection device described in the utility model above with reference to accompanying drawing.But, it will be appreciated by those skilled in the art that the magnet detection device that above-mentioned the utility model is proposed, various improvement can also be made on the basis not departing from the utility model content.Therefore, protection domain of the present utility model should be determined by the content of appending claims.
